Let's divide 66151007 by 490
The aim is to understand the frequency of 490 in 66151007.

Going ahead to step 1:
The number 490 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 490

Moving on to step 2:
When dividing 66 by 490, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 490

Going ahead to step 3:
If we divide 661 by 490, we get 1 and a remainder of 171.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 171 after subtracting 490 from 661.
Append the next digit (5) from the dividend to 171 and continue with: 1715 / 490

On to step 4:
When dividing 1715 by 490, we get 3 with a remainder of 245.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1470 from 1715 leaves us with 245.
Grab the next digit (1) from the dividend, add it to 245, then carry on: 2451 / 490

On to step 5:
490 can be fit into 2451 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtract 2450 from 2451 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 490

Going ahead to step 6:
If we divide 10 by 490, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1350.0
Subtract 0 from 10 to get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 490

Going ahead to step 7:
490 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 13500.0
Subtract 0 from 100 to get 100.
Append the next digit (7) from the dividend to 100 and continue with: 1007 / 490

On to step 8:
1007 divided by 490 is 2 with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 135002.0
Subtracting 980 from 1007 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
The number 490 fits into 270 0 times, leaving a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 135002.0
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
When dividing 2700 by 490, we get 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 135002.05
The remainder is 250 after subtracting 2450 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
490 can be fit into 2500 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 135002.055
If we subtract 2450 from 2500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 135002.055 and a remainder of 0.005.
